How good is our air? New information available from app and UBA website
|The app has up-to-date information about particulate matter, nitrogen dioxide and ozone pollution.
How good is the air that we breathe? Since the end of August, reliable and up-to-date information has been available from Luftqualität [Air Quality], the free and ad-free app of the German Environment Agency (UBA) for Android and iPhone devices. The app posts hourly updated data on harmful pollutants such as particulate matter (PM10), nitrogen dioxide and ozone. The data is collected from more than 400 air quality measuring stations across Germany. An air quality index (AQI) ranging from "very good" to "very poor" also provides an instant view of the air quality at every station. Depending on the data reported, the app issues health advice about doing outdoor activities. Users can choose to receive warning alerts when air quality is poor.
Together with the launch of the app, UBA has upgraded its air data web portal in an even clearer design. A new feature is the air quality index which, just as the app does, provides a quick overview of current conditions. It also offers diagrams of AQI trends from past to present. The air data portal has maps of Germany which show the concentrations of one of five air pollutants (particulate matter, nitrogen dioxide, ozone, sulphur dioxide, carbon monoxide) in specific regions and on specific days, and in some cases times of day. There is also an ozone forecast for the current day and a two-day outlook. The measured concentrations for all five pollutants are up-to-date but historical data is also available. Users can look up data for several stations or pollutants and time periods. Results can also be downloaded. Tables of exceedances of the short-term limit and target values for particulate matter (PM10), nitrogen dioxide and ozone can be generated for the current year. An annual tabulation option enables users to compare annual mean values from earlier years for each pollutant, going back to 2000. Furthermore for any year and pollutant, the tables show data on exceedances of limit and target values at every station.
